Car Repair




The best way to care for your car or truck is to follow the service intervals that your vehicle's manufacturer recommends. Collins Muffler & Service has the tools and expertise to make sure your ride runs exactly as its manufacturer intended it to. From reminding you about routine service intervals to ensuring that all fluids, filters, and hoses are in optimal condition, We take care of your vehicle and leave you with one less thing to worry about.



As time goes by, various auto repair and maintenance needs come up at different intervals. Most manufacturers recommend car maintenance in intervals of 30,000 miles. This is the 30/60/90K mile schedule (issued by the manufacturers to car owners). Trust the experts at Collins Muffler & Service to keep you on schedule, and help you preserve the condition of the vehicle, optimize its performance, and increase its resale value. The 30/60/90K service includes the following:

  • Fluid replacements

  • Oil and Filter changes

  • Inspection of parts and systems - gears, tires, brake pads, belts, hoses, etc.

  • With higher mileage: spark plugs, belts, timing belts when applicable

To keep running smoothly, your car highly relies on oil, lube, and oil filters. Oil helps in lubricating, cooling, and cleaning the internal engine components. With time, motor oil becomes contaminated. Your car needs an oil, lube, and filter change every three months (or 3,000 miles). When it is time for a lube, oil, or filter change,bring your vehicle to Collins Muffler & Service in Greeley Colorado.



No one wants to ride in an uncomfortable car. As the shock absorbers, struts and springs wear out over time, ride comfort will begin to diminish. Ignoring suspension repairs not only negatively affects ride comfort, but also results in excessive tire wear, decreased stability and handling.

The ASE certified technicians at Collins Muffler & Service perform high-quality suspension repair to maximize your car’s ride comfort and enhance driver safety. Whether you drive a compact car or a raised pickup truck, a thorough suspension inspection is performed on shock absorbers, struts, and springs, followed by an explanation of problems, and suspension repair recommendations.
We carry a complete line of high quality suspension parts. Suspension repairs include: replacing damaged, missing, worn shocks, springs, struts, and other suspension parts. If you’re experiencing a bouncy or harsh ride, it’s a good idea to have a suspension inspection performed at Collins Muffler Service.

A car's coolant system transfers excess heat from one part of the engine and finally loses it through the radiator fins. With time, the coolant becomes old and dirty. The old coolant will negatively impact the system's performance. To make sure the system is working effectively, consider having a regular coolant system flush. A coolant flush is basic maintenance for your car's cooling system. Call 970-353-2537 or stop by Collins Muffler & Service



A fan belt, also known as a drive belt, is a belt connecting your car's engine to the front mounted accessories. The fan belt rotates the water pump and engine fan, which maintains a cool environment for the engine and its components. Sooner or later, your vehicle's fan belts will dry out and crack. The mechanics at Collins Muffler & Service will thoroughly inspect your car's belts; replace all worn belts; and adjust the installed belts. Call Collins Muffler & Service for all your vehicle's repair needs.


Hoses transfer coolant and antifreeze throughout the engine's cooling system (including the radiator). Your vehicle's hoses will eventually dry out and crack. We will thoroughly inspect your car's hoses; replace all worn hoses; and adjust the installed hoses. You can count on Collins Muffler & Service for all your vehicle's repair needs.



Not only is it unsafe to drive with burned out lights, it’s also illegal. Don’t wait for your headlights to dim and burn out before you replace them. Most headlights will dim over time and replacing them regularly will ensure the best lighting performance.

Also, replacing your headlamps or taillights in pairs can help you avoid uneven illumination, which can reduce your driving visibility.
